The battery on the spare key fob of my 2000 LS430 is flat but I note from the owner's handbook that I need to take the key fob to the main dealer to get the battery changed. Is it possible to open the key fob yourself and change the battery? Also the rear tail light bulb failure warning light is on constantly but the garage that MoT'd the car cannot find any blown rear bulbs? Is it likely to be a faulty sensor or a bulb they haven't noticed, e.g. lights above number plate? Many thanks in advance
